On the integral simplicial volume of cyclic covers of mapping tori
In this paper, we investigate the asymptotic behavior of the integral simplicial volume of cyclic covers of manifolds that fiber over the circle with fiber given by an $n$-dimensional torus. By studying the integral filling volume -- an invariant introduced by Frigerio and the first author -- for the monodromy, we establish both lower and upper bounds for the limit of the integral simplicial volume of these covers, normalized by the degree of the covering. These bounds are expressed in terms of…

Weak-strong uniqueness for general cross-diffusion systems with volume filling
The weak-strong uniqueness of solutions to a broad class of cross-diffusion systems with volume filling is established. In general, the diffusion matrices are neither symmetric nor positive definite. This issue is overcome by supposing that the equations possess a Boltzmann-type entropy structure, which ensures the existence of bounded weak solutions. In this framework, general conditions on the mobility matrix are identified that allow for the proof of the weak-strong uniqueness property by me…

The Impact of Sanctions on decentralised Privacy Tools: A Case Study of Tornado Cash
This paper investigates the impact of sanctions on Tornado Cash, a smart contract protocol designed to enhance transaction privacy. Following the U.S. Department of the Treasury's sanctions against Tornado Cash in August 2022, platform activity declined sharply. We document a significant and sustained reduction in transaction volume, user diversity, and overall protocol utilization after the sanctions were imposed. Our analysis draws on transaction data from three major blockchains: Ethereum, B…

1,000 Swiss glaciers already gone, and the melting is speeding up #Switzerland

1,000 Swiss glaciers already gone, and the melting is speeding up
Swiss glaciers lost nearly 3% of their volume in 2025, following a snow-poor winter and scorching summer heatwaves. The melt has been so extreme that some glaciers lost more than two meters of ice thickness in a single season. Scientists caution that the decline is destabilizing mountains, raising risks of rock and ice avalanches. Long-term monitoring efforts are now more critical than ever.

On 31 March 2026, University College London will be hosting a Festschrift Symposium for Professor M. Angela Sasse, to recognise and celebrate her contributions to the field of Computer Science and human-centred security specifically. We are seeking scientific contributions to a volume that will be presented at the event. Submissions will be selected by a committee of her students and colleagues, with accepted papers being made available online following the event.

Evolution of wartime discourse on Telegram: A comparative study of Ukrainian and Russian policymakers' communication before and after Russia's full-scale invasion of Ukraine
This study examines elite-driven political communication on Telegram during the ongoing Russo-Ukrainian war, the first large-scale European war in the social media era. Using a unique dataset of Telegram public posts from Ukrainian and Russian policymakers (2019-2024), we analyze changes in communication volume, thematic content, and actor engagement following Russia's 2022 full-scale invasion. Our findings show a sharp increase in Telegram activity after the invasion, particularly among ruling…

Understanding the interplay of collagen and myocyte adaptation in cardiac volume overload: a multi-constituent growth and remodeling framework

Understanding the interplay of collagen and myocyte adaptation in cardiac volume overload: a multi-constituent growth and remodeling framework
Hearts subjected to volume overload (VO) are prone to detrimental anatomical and functional changes in response to elevated mechanical stretches, ultimately leading to heart failure. Experimental findings increasingly emphasize that organ-scale changes following VO cannot be explained by myocyte growth alone, as traditionally proposed in the literature. Collagen degradation, in particular, has been associated with left ventricular adaptation in both acute and chronic stages of VO. These hypothe…

Direct observation of the X-ray counterpart of the H{\alpha} filaments and of the sloshing spiral in the Perseus galaxy cluster

Direct observation of the X-ray counterpart of the Hα filaments and of the sloshing spiral in the Perseus galaxy cluster
Deep Chandra observations of the Perseus galaxy cluster have allowed for the discovery of X-ray counterparts to the Hα filamentary structures and of a sloshing spiral. However, both components are extremely faint, and their study is largely hindered by the volume-filling hot intracluster medium (ICM). Using the Poisson General Morphological Component Analysis (pGMCA) algorithm, a blind source separation method adapted for Poissonian statistics, we were able to extract detailed, clean morpholog…
